I am greatful for this summary, as I usually check the comments before the link, to see if its worth to click through the cookie consent and Ad spam found on most sites, as well as digging out punchlines from lengthy articles.

The linked site is GitHub which has neither of those things.

I don't change habits depending on the site that is linked. And I appreciate a summary in the comments.

I don't think I have ever made it past the comments on here, so I found it pretty helpful.

I really liked he did that, completely changed the perspective on the comments. I never click on links.

Even if he did not improve as much as he did our discussion, did you have to be so mean. It's Christmas, let him have it.

Why don't you click on links?

I find it valuable to skim the original article first before I'm swayed by commenters opinions.

Not everyone participates in Christmas. This fact is a manifestation of classical liberalism: religious freedom in particular.

I see your account is 1 day old, and your question makes total sense to me too.

So, welcome, glad to have you here of course.

The answer is a commented "tldr" is widely used on news.ycombinator.com, and, as comments below say, it's become a conventional courtesy: people tend to scan comments for tldrs, in order to possibly avoid digressing into commonly (but not always) long winded posts.

FWIW I’ve been around for ages and I routinely browse the comments to get signal on whether or not the linked content is worthwhile.

yep same here: have been here since before it started, and the new person didn't realize such.

Right, but to not even open the linked page when it is so tiny seems an obvious mistake.
